Introduction to Streams API
Java Streams is a powerful feature introduced in Java 8 that allows developers to process collections of data in a functional programming style.
A stream is a sequence of elements processed in parallel or sequentially.
Streams provide a concise and expressive way to manipulate collections of data by allowing developers to define a pipeline of operations that can be performed on the elements of the stream.
The pipeline typically consists of three parts:
- a source,
- zero or more intermediate operations,
- and a terminal operation.
The source of a stream can be a collection, an array, an I/O channel, or any other data source.
Intermediate operations, such as
sorted() transform and filter the elements of a stream to produce a new stream. Finally, a terminal operation, such as
collect(), performs a final action on the elements of the stream and produces a result.
The beauty of streams is that they allow developers to perform complex operations on collections of data in a single line of code and can easily leverage multi-core architectures for parallel processing to achieve better performance.
Note: Streams are a powerful tool for working with data collections in Java.
